A company managed by billionaire insurance magnate William R. Berkley and equity fund manager Bruce Berkowitz acquired a collection of properties in Miami’s Coconut Grove at bankruptcy auction for $5.4 million.

The “mystery” buyers who won six sought after West Coconut Grove lots in U.S. bankruptcy court are not so mysterious after all: They are well known Miami financial figures Bruce Berkowitz and Bill Mahone.

Using the Internal Revenue Service (IRS) as the “triggering creditor” under § 544(b) of the Bankruptcy Code provides a powerful tool for bankruptcy trustees to reach back for periods of 10 or more years in the pursuit of fraudulent conveyances that are otherwise outside the applicable state law statutes of limitation.

Glenn Beck’s media outlet TheBlaze.com told the Delaware Chancery Court on Monday that it should halt proceedings in a suit its former CEO brought against the company — seeking an order that it foot the defense bill for a related Texas suit accusing him of mismanaging Beck’s production company — characterizing it as “forum shopping.”

The former CEO of Glenn Beck’s news outlet TheBlaze Inc. on Wednesday asked a Delaware court to order the company to foot the bill for a suit accusing him of mismanaging Beck’s production company, just days after TheBlaze asked a Texas state court to do the opposite.
